LMR14203 short-cicuit current is too high

I bought the TI LMR14203 Demo board to evaluate the component for a new design in my company and it wors fine. In my application I need that the short-circuit current be well controlled in the range 0.4A to 0.8A. But with the demo board the short-circuit current is quite far the 2A (for one or two seconds and than I cut off); the unit don't blow-up and is always running. I don't undertand this wery high current, when the data-sheet of the chip states clearly a quite lower value. (Sorry, but English is not my first language). Could someone help to understand that behaviour? Thank, Enrico.
